BELT PUNCH AND GUIDE.

Application filed November 16, 1921.

To all 1072,0222. it may concern:

Be it known that I, IVILLIAM W. BEW- emit, a citizen of the UnitedStates, residing at Shelby, in the county of Richland and State of Ohio,have invented certain new and useful Improvements in Belt Punches andGuides, of which the following is a specification.

This invention relates to jigs, and particularly to such devices -foruse in the punching of belt hook holes in round belting.

The objects of the present invention are to provide a new and improvedig by means of which a belt hook hole may be easily and quickly pun-shedin a round belt, at a fixed and predetern'iined point; which insures thepassage of said hole through the longitudinal axis of the belt; andwhich is simple in construction and can be manufactured withoutdifficult or expensive production methods.

Further objects of the invention are in part obvious and in part willappear more in detail hereinafter.

The invention comprises he construction and arrangement of partshereinafter des: ribed and claimed.

In the drawings, Fig. 1 is a side elevation, showing the in properposition on a round belt for the punching of a hole therein; Fig. is across section on the line 22, 1, but with the punching member driventhrough the belt; Fig. 3 is a perspective view of the jig; and Fig. l isa plan view thereof.

Referring to the drawings, the comprises a relatively small wooden block1, although said block may be made of any other suitable material, suchas metal, if desired. In the bottom of said block is a longitudinallydisposed groove 2, substantially U- shaped in cross section, forming aseat for the belt 3, and in which said belt is securely held during thepunching operation. In the upper face of said block, and equidistantfrom the ends thereof, is a hole or opening l extending downwardlytherethrough and forming a guide way for the hole punching member 5,which may be a nail or the like. The upper side edges of the block arebeveled off, as at 6, to provide convenient places for grasping andholding the block during the punching operation.

In the use of the device, the belt 3, in

Serial No. 515,603.

which a belt hook hole is to be punched, is laid upon a table or anyother suitable support. The block 1 is then seated upon the belt, asindicated in Figs. 1 and 2, with either end of said block flush with oneend of the belt. In seating the block on a round fabric belt, in whichthere are rows of stitches, care should be exercised to see that thepunch guide Way 4 lies between the rows and not over one, so that thepunching of the belt hook hole will not break the stitching andconsequently weaken the belt.

The belt is held against rotation or distortion during the punchingoperation by holding the block 1 firmly on the belt, which in turn issecurely held against the support on which it rests. The punching member5 is then inserted in the guide Way 4:, in which it will rest in anupright position, so that it may be easily and quickly driven throughthe belt, after which it may be readily withdrawn.

Thus it will be seen that I have provided a jig by means of which a belthook hole may be easily and quickly punched in a round belt; whichinsures the passage of said hole through the longitudinal axis of thebelt and thus precludes the possibility of weakening the belt byimproperly punching the hole; and which also insures the punching of thehole at a proper distance from the end of the belt, in actual practicethis distance being about three-sixteenths of an inch1 when athree-sixteenth inch belt is use Further objects of the invention willbe apparent to those skilled in the art to which it relates.

Having described my invention, I claim:

A device for positioning a substantially round belt and punching holestherein, comprising a block provided with a cut-out portion forming aseat for positioning engagement with the belt, and a hole-punchingmember, said seat comprising a curved portion and side leg portions andhaving an engaging surface of substantially the same form as that of thebelt, the depth of said cut-out portion along the axis of the punchingmember being less than the diameter of the belt.

In testimony whereof I hereby afiix my signature.

WILLIAM W. BEWSICK.
